Well I Know it installs ok on that operating system as we load it on all new installations.:thumb:

Does it download in full if you save it to disk rather than run from download?

Are you upgrading over a previous , earlier, installation of Acrobat?

If you are, try uninstalling the old version first.

Tried both ways, I now have the download file on my desktop. I had no version in then in desperation I put version 5. something in. Odd, as Windows says there are "known issues" with that version it seems to work ... up to now. :Rofl1:

:Rofl1: There is a Vista Service Pack out now. Hopefully it will sort out a lot of the issues. I think a very common problem is the amount of RAM Vista needs. People try to run it in 512MB and it performs like treacle, but who can blame them, Laptops are often sold with Vista installed on 512MB ram anyway!

As for Adobe... Might be an idea to see if an 'orphan' copy of Adobe is still running by opening Task manager and looking through the process's for AcroRd32.exe when you think no Adobe's are running. If you see one then there is an instance running.
